Hi Danny,

Yep, the VirtSite's MX can point BACK to itself.  Although not strictly necassary, it works best that way it seems.

typically I set up A and MX records like so;

 A   mydomain.com.       -->    111.222.111.222
 A   mail.mydomain.com.  -->    111.222.111.222
 A   www.mydomain.com.   -->    111.222.111.222
 MX  mydomain.com.       -->    30 mydomain.com.

Then I tell my users to collect their mail and enter "mail.mydomain.com" in BOTH the pop3 & SMTP server boxes in their mail client.   They could if they wanted, enter **ANY** A record entry that is on that IP address.  Even another Domains MAIL.OTHERDOMAIN.COM could be used, and ONLY their **OWN** mail is still available to them, NOT others mail.

Anyway that a nice and simple setup that DEFINATLY works on a Raq3 !!

Have Fun!
